我在plsql中创建一个程序它返回此错误任何人都知道它我发布我的代码和错误快照在这里

    CREATE OR REPLACE PROCEDURE CHR.ATT_INSERT_TEST
IS
   CURSOR ATT
   IS
      SELECT   emp.EMPLOYEE_ID EMPLOYEE_ID,
         io.CHECKTYPE CHECKTYPE,
         io.MACHINE_NUM MACHINE_NUM,
         io.ATT_ID ATT_ID, 
         io.SWIPE_DATE SWIPE_DATE,
         io.SWIPE_TIME SWIPE_TIME
  FROM   INOUT_LIVE_MACHINE_TEST io, CHR_EMGT_EMPLOYEE emp
 WHERE   emp.EMPLOYEE_CODE = io.EMPLOYEE_CODE
 AND io.ATT_ID NOT IN (SELECT   ATT_ID_REF
                                 FROM   CHR_TA_EMP_SWIPE_IN_OUT
                                WHERE   io.ATT_ID = ATT_ID_REF);
BEGIN
   FOR I IN ATT
   LOOP
      INSERT INTO CHR_TA_EMP_SWIPE_IN_OUT (EMPLOYEE_ID,
                                           SWIPE_DATE,
                                           SWIPE_TIME,
                                           SWIPE_ID,
                                           SWIPE_TYPE,
                                           CREATED_BY,
                                           CREATION_DATE,

   END LOOP;

这是我的程序，我主要是时间制作子查询，但这次它给我带来了这种错误。我认为这个错误显示一些问题是关于别名，但我已经为每列定义了别名我读了这篇文章，但我的代码仍然存在

PLS-00402: alias required in SELECT list of cursor to avoid duplicate column names

这是我的表结构

CREATE TABLE CHR.CHR_TA_EMP_SWIPE_IN_OUT
(
  EMPLOYEE_ID       NUMBER(10)                  NOT NULL,
  SWIPE_DATE        DATE                        NOT NULL,
  SWIPE_TIME        DATE                        NOT NULL,
  SWIPE_ID          NUMBER(10)                  NOT NULL,
  SWIPE_TYPE        VARCHAR2(1 BYTE),
  CREATED_BY        NUMBER(10),
  CREATION_DATE     DATE,
  LAST_UPDATED_BY   NUMBER(10),
  LAST_UPDATE_DATE  DATE,

CREATE TABLE CHR.CHR_EMGT_EMPLOYEE

  EMPLOYEE_CODE              VARCHAR2(30 BYTE)  NOT NULL
  )



CREATE TABLE CHR.INOUT_LIVE_MACHINE_TEST

  ATT_ID         NUMBER,
  USERID         NUMBER,
  EMPLOYEE_CODE  NUMBER,

Answer 1

您的程序没有错误。只有问题出现在你的表格中＃IN; INOUT_LIVE_MACHINE_TEST＆＃34;。它缺少SWIPE_DATE＆amp; SWIPE_TIME列。请参阅下面的工作演示。

创建了包含以下列的表格：

CREATE TABLE INOUT_LIVE_MACHINE_TEST 
(
  ATT_ID         NUMBER,
  USERID         NUMBER,
  EMPLOYEE_CODE  NUMBER,
  SENSORID       NUMBER,
  SWIPE_DATE        DATE                        NOT NULL,
  SWIPE_TIME        DATE                        NOT NULL,
  MACHINE_NUM    VARCHAR2(20 BYTE),
  CHECKTIME      VARCHAR2(20 BYTE),
  CHECKTYPE      VARCHAR2(20 BYTE)
)

程序已编译：

CREATE OR REPLACE PROCEDURE ATT_INSERT_TEST
IS
   CURSOR ATT
   IS
      SELECT   emp.EMPLOYEE_ID EMPLOYEE_ID,
         io.CHECKTYPE CHECKTYPE,
         io.MACHINE_NUM MACHINE_NUM,
         io.ATT_ID ATT_ID, 
         io.SWIPE_DATE SWIPE_DATE,
         io.SWIPE_TIME SWIPE_TIME
  FROM   INOUT_LIVE_MACHINE_TEST io, CHR_EMGT_EMPLOYEE emp
 WHERE   emp.EMPLOYEE_CODE = io.EMPLOYEE_CODE
 AND io.ATT_ID NOT IN (SELECT   ATT_ID_REF
                                 FROM   CHR_TA_EMP_SWIPE_IN_OUT
                                WHERE   io.ATT_ID = ATT_ID_REF);
BEGIN
   FOR I IN ATT
   LOOP
      INSERT INTO CHR_TA_EMP_SWIPE_IN_OUT (EMPLOYEE_ID,
                                           SWIPE_DATE,
                                           SWIPE_TIME,
                                           SWIPE_ID,
                                           SWIPE_TYPE,
                                           CREATED_BY,
                                           CREATION_DATE,
                                           CLIENT_IP)
        VALUES   (I.EMPLOYEE_ID,
                  TO_DATE (i.SWIPE_DATE, 'MM/DD/YYYY'),
                  I.SWIPE_TIME,
                  CHR_TA_SWIPE_IN_OUT_SEQ.NEXTVAL,
                  I.CHECKTYPE,
                  I.EMPLOYEE_ID,
                  TO_DATE (i.SWIPE_DATE, 'MM/DD/YYYY'),
                  '192.168.0.71'
                  );
   END LOOP;
COMMIT;
END;
